Abstract

Abstract Translated from French Le fonctionnement du palier hydrostatique pour pompes à fluide sous pression, alimenté au moyen du fluide pompé est assuré quelles qui soient les conditions règnant dans la pompe. A cet effet, les gicleurs (14) d'alimentation en fluide des alvéoles (9) du coussinet (4) du palier sont connectés en amont aux deux compartiments (7, 8) de la pompe où se trouve le fluide sous deux pressions différentes par l'intermédiaire d'un clapet à bille (17), et deux chambres de détente (18, 19), ménagées dans le coussinet (4) de part et d'autre des alvéoles (9) sont connectées en aval aux deux compartiments (7, 8) par l'intermédiaire de clapets à bille (22, 23). The operation of the hydrostatic bearing for pressurized fluid pumps, supplied by means of the pumped fluid is ensured whatever the conditions prevailing in the pump. To this end, the nozzles (14) for supplying fluid to the cells (9) of the bearing pad (4) are connected upstream to the two compartments (7, 8) of the pump where the fluid is located under two different pressures. by means of a ball valve (17), and two expansion chambers (18, 19), formed in the cushion (4) on either side of the cells (9) are connected downstream to the two compartments (7, 8) by means of ball valves (22, 23).
